This episode of Park Predators examines the 1928 disappearance of newlyweds Glenn and Bessie Hyde, who vanished while attempting to raft down the Green and Colorado Rivers through the Grand Canyon. The host, Delia D'Ambra, explores the enduring century-old mystery by drawing on author Brad Dimick's 2001 book and historical records, detailing the couple's preparations, their journey, and the intense search efforts triggered by their families. While conventional wisdom points to a tragic river accident, various rumors, a disputed confession from a tourist in the 1970s, and a cold case skeleton found in a photographer's boathouse have fueled speculation of foul play, survival, or a darker secret.
The episode highlights how the couple's lack of life jackets, aggressive scheduling, and strained dynamics captured contemporary media attention before they vanished near River Mile 95. When their abandoned scow was recovered intact with supplies and Bessie's journal, speculation grew about whether they drowned, fled, or encountered violence. The narrative weighs theories involving an estranged ex-husband, family suspicions, and a tourist who claimed decades later to have killed her husband on the trip, concluding that the eventual damming of the river and destruction of original evidence leave the true fate of the honeymooners perpetually unresolved.

A Shocking Campfire Confessionstory
An older woman named Liz claimed to tour guides around a campfire in 1971 that she was Bessie Hyde and had stabbed her abusive husband to death.
“The puzzling disappearance of newlyweds Glenn and Bessie Hyde in the fall of 1928 is a mystery that, just like the landscape and waterway they vanished from, has taken many ups and downs over the decades.”
“The wooden scowl that was presumed to belong to Bessie and Glenn had been found adrift near an area of the Colorado River known as Diamond Creek.”
“The original journal then went to Glenn's sister, Jean, who later destroyed it after writing her own version of it.”
“In 1935, that project was completed, and Lake Mead flooded the river in the exact area where the Hides boat had been found in 1928.”
A couple sets out on a honeymoon adventure to conquer the mighty Colorado River, but their journey ends when they vanish without a trace.
